Two hundred sixty-four patients exhibiting renal artery occlusive disease underwent operation for renovascular hypertension between 1961 and 1977. Included were 27 pediatric patients. Fibrodysplastic disease affected 132 adults. Atherosclerotic lesions affected 51 patients with and 54 patients without clinically overt extrarenal arteriosclerotic cardiovascular disease. Ischemic kidney renin hypersecretion (renal: systemic index greater than 0.48), associated with suppressed contralateral kidney renin secretion (renal: systemic index approaching 0.0) predicted curability most reliably. Three hundred forty-eight operations were performed, of which 297 were primary and 51 were secondary procedures. Nephrectomy was initial therapy in 15 cases. Three operative deaths occurred among 51 patients manifesting overt extrarenal arteriosclerotic disease. No operative mortality was encountered among the other 213 patients. Surgical benefits were afforded 96% of pediatric patients and adults with fibrodysplastic disease, 91% of patients with focal renal arteriosclerosis, and 73% of those exhibiting overt extrarenal arteriosclerosis.

Liver and kidney samples obtained from 76 autopsies were analyzed for cadmium and zinc content. The patients had died of various internal diseases. None of them had any known occupational exposure to cadmium. A record was made of age, sex, place of residence, diagnosis, and smoking habits of each patient. The results showed no significant correlation between cadmium accumulation and hypertension or cardiovascular disease. There was, however, a significantly higher kidney cadmium level in smokers than in nonsmokers.

The high incidence, great import, and long duration of cardiovascular diseases are reflected in high demands placed on the health services. Experience shows that utilization of the results of research in general practice is lagging behind. The application of any improvement in the diagnosis, therapy, and prevention in health care waits several years for its accomplishment. In order to improve this situation, the Ministry of Health of the CSR constituted, in line with WHO recommendations, a Department for Cardiovascular Diseases Control. The Department has worked out a programme of prevention and control of the major cardiovascular diseases, in particular, ischaemic heart disease, systemic hypertension and its complications, rheumatic heart disease, congenital cardiac and vascular defects, and cor pulmonale. New diagnostic, therapeutic, and preventive procedures are first tried out in so-called model areas and are only after this introduced into the national health care of people suffering from or endangered by cardiovascular diseases. In parallel, organizational measures necessary for comprehensive care are implemented. The authors report on the experience gained so far with the realization of the programme of care of people suffering from IHD and acute myocardial infarction. They emphasize the importance of continual schooling of medical personnel and of health education of the entire population. They describe the implementation on a national scale of postgraduate cardiological courses intended especially for first-line doctors.

The reliability of casual blood pressures for reflecting blood pressure status and predicting cardiovascular sequelae of hypertension was examined in the Framingham cohort of 5209 men and women followed for 18 years. Blood pressures were more variable in persons with higher levels. After controlling for pressure level the degree of variability in an individual at one point in time did not correlate with the degree of varability at another time. Although a single casual measurement does not afford a precise characterization for an individual it was found to be highly predictive of future cardiovascular disease. A series of blood pressure measurements (averaged) improved the predictability somewhat but this seemed to be fully explicable by the greater stability of an average of several measurements as against a single measurement.

After a foreword concerning the present interest for the epidemiology of arterial hypertension mainly in relationship with the prevalence of the condition, its recognition in the general population and its systematic treatment, three separate chapters show the distribution of arterial blood pressure, its mean values and the prevalence of hypertension collected by three research groups: the Centre for Cardiovascular Diseases, St. Camillo Hospital, Rome, with 8 population groups (6929 subjects of whom 447 women, aged 20 to 64, belonging to the city of Rome and to other locations of 5 different regions); the II Medical Clinic, University of Padua, with 2 population groups (5852 men and women aged 20-64, belonging to a defined area of Veneto); the Research Group of the Roman Project of Coronary Heart Disease Prevention, with 2 population groups (2611 men aged 40-59, from Rome). The data provide a description of some characteristics of blood pressure and hypertension in different Italian areas and population groups and show the existence of large differences in the mean values of blood pressure and in the prevalence of hypertension, also within the country.

One case with Wallenberg's syndrome followed by the neck clipping of the posterior inferior cerebellar aneurysm was reported. The patient was 49 years old female with the subarachnoid hemorrhage, who had previously no history of the cardiovascular disease. The vertebral angiogram revealed a saccular aneurysm of the left vertebral artery at the origin of the posterior inferior cerebellar artery. The preoperative neurological examination were normal, except for the slight degree of the meningeal irritation. The surgical intervention was successfully performed on 39th day after the subarachnoid hemorrhage. Postoperative course was eventful, presenting the typical Wallenberg's syndrome, which was complicated the accompanying signs. The troublesome accompanying signs were chiefly automatic respiratory dysfunction (sleep-induced dyspnea), autonomic dysfunction (Horner's syndrome, perspiration, hypertension), and restless confusion. The postoperative vertebral angiogram showed the obliteration of the aneurysm and the sufficient circulation of the vertebrobasilar system, especially the posterior inferior cerebellar artery. The mechanism of "sleep-induced dyspnea" was discussed in detail from the literatures. In addition to the above mentioned, it should be stressed that the recognition of "sleep-induced dyspnea" and the other accompanying signs are important for the treatment of the patient with the brain stem lesion.

The incidence of cardiovascular disease risk factors and other indicators of cardiac impairment were studied in 478 patients prior to their aortocoronary vein bypass operation and 194 patients who had angiographic examination but did not undergo the operation because the clinical and coronary angiographic findings were not considered serious enough to warrant the bypass procedure. The patients referred for surgery had higher plasma cholesterol and triglyceride levels (259 and 219 vs 233 and 180 mg/100 ml), tended to be older (53 vs 49 years) and had more extensive occlusive disease (occlusion score 200 vs 70) than the group without the operation. There was little difference in the proportion of smokers (81 vs 83%) or prevalence of hypertension (33 vs 30%). In comparison with 9,964 participants of a local health screening program, both patient groups had markedly higher prevalence of smoking, hypertension, chest pain and previous myocardial infarcts.

In conclusion, patients on chronic maintenance dialysis have an increased incidence of death from cardiovascular disease. Hypertension plays a major role, and these patients must be carefully monitored for complete control of blood pressure. Adequacy of ultrafiltration to maintain normal extracellular volume is an essential part of the dialytic treatment. Hypertensive patients should be screened for excessive renin secretion because of its possible role in unresponsive hypertension in patients on dialysis. Nephrectomy should be used when necessary, where dialysis and antihypertensive medication have not adequately controlled blood pressure. Patients must be monitored for the presence of pericardial disease to avoid subsequent pericardial effusion and the development of constrictive pericarditis with its adverse effect on myocardial function. When constrictive pericarditis is present, it obviously should be relieved by appropriate surgery. Efforts should be made to minimize cardiac output in hemodialysis patients. Whether or not routine transfusions to maintain a higher hematocrit are indicated is a question that cannot yet be answered. However, patients with marginal cardiovascular function who are accepted on hemodialysis and must have an arteriovenous shunt should be supported in any manner to minimize an increase in cardiac output. Early and aggressive treatment of known episodes of sepsis is important in the elimination of valvular endocarditis in this patient population. Perhaps one of the finer indicators of adequacy of hemodialysis will be K rate and peak immunoreactive insulin levels. Continued abnormality of these parameters may contribute to cardiovascular disease. Clearly, further study of the effect of abnormal carbohydrate metabolism on lipid metabolism is in order. Serum triglyceride, serum cholesterol and lipid electrophoretic pattern should be followed to evaluate the beneficial effects of drug therapy and changes in dialytic technique on the development of cardiovascular disease. Careful monitoring of calcium, phosphorus, bone films and parathyroid hormone levels is indicated to assess parathyroid status. The use of aluminum binders and parathyroidectomy to prevent vascular and myocardial calcification is important in the therapy of these patients. The use of cardiac catheterization, coronary artery arteriography, and possibly cardiac vascular repair, should be considered in the chronic hemodialysis patient with coronary artery disease if he is otherwise well. Adequacy of hemodialysis perhaps can be evaluated through its effect on all of the above parameters. Whether or not changes in artificial kidney treatments can correct the final vascular disease remains to be seen.

1. There were significant correlation between hyperlipidemia and obesity, hypertension, abnormal ECG and abnormal eyeground. 2. The incidence of cerebral hemorrhage was closely associated with hypertension but not with hyperlipidemia. 3. It was proved that hypertension with both hyper-Ch and hyper-TG was highly related to the development of cerebral infarction. 4. It seemed that the incidence of myocardial infarction and angina pectoris was related to hypertension with hyper-Ch. 5. Therefore, the present study suggested that the control of hypercholesterolemia and hypertriglyceridemia was useful for the prevention of cerebro-cardiovascular disease.

A new radiologic index indicative of pulmonary artery hypertension is presented. It was obtained by measuring the horizontal distances from the midline to the first divisions of the right and left pulmonary arteris, and dividing the sum of these distances by the maximum transverse diameter of the thorax. The index was significantly different in groups with and without pulmonary hypertension and was abnormal (above 38 percent in 111 of 150 patients with cardiovascular disease and pulmonary arterial hypertension (PAH). None of the cases with increased pulmonary flow from cardiac shunts but normal PAP had an anbormal index. Thus, an abnormal index suggested PAH but correlated poorly with the extent of hypertension.
